The Voluntary Product Accessibility Template®, or VPAT®, is a tool used to document a product's conformance with the accessibility standards under Section 508 of the Rehabilitation Act. The purpose of the VPAT is to assist Federal contracting officials and other buyers in making preliminary assessments regarding the availability of commercial "Electronic and Information Technology" products and services with features that support accessibility. You can read more about VPAT at the Information Technology Industry Council website.
